| 摘 要： | 近年来对金矿石的制样研究认为，金测定精密度和准确度较低的主要原因是样品加工中存在的问题。因此，研究不同类型的金矿石制样，改进加工流程，是保证金分析质量的前提．通过对甘肃李子园、小沟里、三洋坝等秦岭山脉区的粗颗粒性金矿石的制样研究，制定出了比较合理的制样流程。

| Abstract: | According to recent years' study in gold ore sample preparation, the lower precision and accuracy of gold determination was mainly caused by some matter in sample preparation process. Therefore studying sample preparation procedures for different types of gold ore and improving preparation flow is a precondition to ensure analyzing quality. A reasonable sample preparation flow chart has been designed through a research on coarser grain gold ore in Qinglin rang such as Liziyuan, Xiaogouli and shanyangba area etc. |

| Keywords: | gold ore uniformity representativeness geological sample |
